2 Claims.

This invention appertains to new and useful improvements inhoisting apparatus and more particularly to an apparatus for conveniently applying and removing heavy valve sections, and

more particularly the heavy types of valves such as are used onrailroad rolling stock. The valves on railroad rolling stock are generally known as triple valves and each involves anemergency unit and an equalizing unit, each of which weighs over one hundred pounds. Many workmen are ruptured or otherwise injured through the handling of these heavy items.

The principal object of the present invention is to provide an applying and removing apparatus which can be conveniently set up for permitting removal of the valve sections or units and the lowering of the sameto the ground or to the level of some conveyance.

Another important object of the invention is to provide a valve applying and removing apparatus which can be easily adjusted and operated as requirements demand.

Other objects and advantages of the invention will become apparent to the reader of the fol- 25 lowing specification.

In the drawings:

Figure 1 represents a side elevational view of a triple valve assembly showing the applying and removing apparatus in use. v

Figure 2 is an end elevational view of the valve and apparatus applied.

Figure 3 is a top plan view of the apparatus alone.

Figure 4 is a sectional View on the line 44 of Figure 3.

Figure 5 is a section on the line 5-5 of Figure 3. 1

Figure 6 is a section on the line 6-6 of Figure 3.

Referring to the drawings, wherein like numerals designate like parts, it can be seen that numeral 5 generally refers to the triple valve, numerals 5 and I generally referring to the emergency and equalizing units thereof. Numeral 8 denotes the central shell of the valve assembly. The unit 6 is removable from the shell 8 by the bolts 9, While the elongated bolts H] of the unit I serve to secure the unit 1 in place.

In carrying out the present invention, a bracket generally referred to by numeral H is employed. This bracket consists of the U-shaped frame l2 having the diagonally disposed brace bar l3 therein. The leg portions of the frame l2 are horizontally disposed, the lower leg having the downwardly disposed end portion l4 secured to the valve shell 8 by a bolt l5, while the upper end of the frame, that is, the upper leg has its end bent upwardly to define the lug l6 and then back downwardly to define the leg ll.

A semi-circular shaped band 18 has its ends swingably connected as at l9 to the valve shell 8 and this is adapted to be swung over the lug It as shown in Figure 2 to hold the bracket H in proper position, while the leg I! is resting on the outstanding portion 8a of the valve shell.

The lifting and lowering means of the invention is generally referred to by numeral 20 and consists of the longitudinally bored barrel 2| through which the screw shaft 22 is disposed. A nut 23 forming the hub for the hand wheel 24 is threadedly disposed on the threaded shaft 22, so that by rotating the wheel, the threaded shaft can be lifted and lowered with the result that the platform assembly generally referred to by numeral 25 will follow accordingly.

The platform apparatus generally referred to by numeral 25 consists of an elongated arm 25, which may be a plank of heavy wood, and the right angularly disposed platform 21. Bearing plates 28 and 29 are provided above and below one end of the arm 26 and secured thereto by bolts 30. The plates 28, 29 and the arm 25 are formed with a bore 3| through which the reduced smooth portion 32 at the lower end of the shaft 22 is disposed. The lower end of the smooth portion 32 is provided with a thread accommodating nut 33 while the shoulder 34 defined by the reducement 32 bears against the upper plate 28.

The other end of the arm 2t has a pair of angle members 35-35 secured in parallel relation thereto by bolts 36. A bridge plate 31 bridges the angle members 35 and through this is disposed the set screw 38 having the hand wheel 39.

Angle members 40 and end plates 4| serve to brace one end of the arm 21 and a bearing plate 42 on the top side of the arm 2'! has the set screw 38 bearing against the same.

The other end of the arm 21, that is, the free end thereof, has the angle iron reinforcement 43 and the adjacent bottom plate 44, this angle member 43 and plate 44 serving to hold a nut 45 against rotation. Through this nut is threadedly disposed the threaded shaft 46 operating in the bore 4'! longitudinally disposed into the arm 21.

Numeral 48 represents the slidable platform which includes a rectangular shaped frame 49 extending around the perimeter of the platform and-provided with a depending skirt 50 at one end and'both longitudinal edges. Cross pins 5! between the depending portions 50 at the side edges of the frame 49 support rollers 52 which ride on the arm 21. As shown in Figure 4, the outer end of the screw shaft 46 has a handle 53 to permit rotation of the threaded shaft 46 and this threaded shaft has a smooth portion 54 journalled through an opening in one end of the frame 49.

It can now be seen, that the arm 21 can be properly set upon the arm 26 by means of the set screw 38, after of course the bracket H has been attached to the Valve shell 8. By operating the hand wheel 24, the platform 48 can be adjusted so as to lift the same upwardly until it engages under the particular unit 6 or I of the valve assembly 5, as suggested in full line and broken lines in Figure 1. After the nuts 9 or 10 have been removed to release the particular unit 6 or 1, the arms 2'6 and 21 can be swung outwardly and lowered by the wheel 24 to the the desired level or to the ground or maintained in a position where they can be checked apart from the shell 8.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. Apparatus for removing and replacing the lower section of a suspended valve from an upper section comprising a tubular barrel adapted to be attached to said upper section in upright position, means to attach said barrel comprising a laterally extending bracket on one side of the same, a screw shaft in said barrel having upper and lower ends extending out of the same, a hand wheel threaded onto the upper end of said shaft and operative to raise and lower the same in said barrel, an elongated arm-like platform pivotally mounted at one end on the lower end of said shaft to extend laterally therefrom and for swinging movement about the shaft to locate its other end into and from subjacent position relative to said lower valve section, a second similar platform mounted on said other end of the first-mentioned platform toextend lengthwise at a right angle thereto and endwise slidable thereon beneath said lower valve section, and manipulative means for sliding said second platform into different set positions.

2. Apparatus for removing and replacing the lower section of a suspended valve from an upper section comprising a tubular barrel adapted to be attached to said upper section in upright position, means to attach said barrel comprising a laterally extending bracket on one side of the same, a screw shaft in said barrel having upper and lower ends extending out of the same, a hand wheel threaded onto the upper end of said shaft and operative to raise and lower the same in said barrel, an elongated arm-like platform pivotally mounted at one end on the lower end of said shaft to extend laterally therefrom and for swinging movement about the shaft to locate its other end into and from subjacent position relative to said lower valve section, a second similar platform mounted on said other end of the first-mentioned platform to extend lengthwise at a right angle thereto and endwise slidable thereon beneath said lower valve section, and manipulative means for sliding said second platform into different set positions, said attaching means comprising an upstanding lug on top of the bracket, and a curved band attachable at its ends to opposite sides of said upper valve section and adapted to hook over said lug.
